  • Transition metal catalyzed polymerization of olefinic monomers in a water-containing polymerization medium
    Patent number: 6506856
    Abstract: Polymers based on monomers having a C—C double bond and/or C—C triple bond are prepared by polymerization of these monomers in the presence of a catalyst system comprising as active constituents a transition metal compound of an early transition metal and, if desired, a cation-forming compound B) and, if desired, further components C), wherein the polymerization mixture contains at least 30% by weight of water.
    Type: Grant
    Filed: December 5, 2000
    Date of Patent: January 14, 2003
    Assignee: BASF Aktiengesellschaft
    Inventors: Lambertus Manders, Marc Oliver Kristen, Alexander Haunschild, Michael Geprägs
  • Aqueous polymer dispersion containing an emulsifier with phosphate groups
    Patent number: 6348528
    Abstract: Aqueous polymer dispersion comprising from 0.1 to 10 parts by weight per 100 parts by weight of polymer of an emulsifier A) having a phosphate group, wherein said emulsifier consists at least 50% by weight of ethylene oxide and propylene oxide groups and the proportion of the ethylene oxide groups and propylene oxide groups is in each case at least 10% by weight, based on the overall amount of the ethylene oxide and propylene oxide groups.
